writerfilter wants to convert incoming RTF and OOXML files into
writer's document model. But it currently has to do so by
manipulating the limited subset that we expose through the UNO
API.
This is both slower and less accurate than having access
to the full document model.
So move it inside, and then we can strip out various hacks, and
optimise imports.
